(CNN) – Welcome to CNN Radio News Day.

The U.N. Security Council has ramped up its economic sanctions against North Korea. They're aimed at restricting the country's cash flow, making it more difficult to conduct nuclear weapons and missile research. CNN Senior U.N. Correspondent Richard Roth says it was no coincidence that the action was taken shortly after Pyongyang said it's prepared to launch a preemptive nuclear strike against the West:

“Diplomats will always be more optimistic, but if you go by the track record this resolution will not change the behavior of North Korea. The rhetoric is certainly escalating from Pyongyang, we've had decades of threats of war, but the technology capabilities have dramatically increased."

On Capitol Hill today a federal bill to toughen laws on gun trafficking passed through a Senate committee. It's the first federal gun control measure to be voted on and leads a parade of bills that are sure to spark some heated debate. Daniel Webster is the Director of the Center for Gun Policy at Johns Hopkins:

"It's through initiatives at the state level that the ideas and the momentum kind of percolate up to the federal level."

The ban on the sale of sugary soft drinks larger than 16 ounces at restaurants, convenience stores and theaters goes into effect in New York next week. CNN’s Steve Kastenbaum checked in with restaurant and bar owners to see how they are dealing with the change. Eric Levine is director of operations for Dallas BBQ, a family owned business with 10 restaurants around the city. He says the ban prohibits him from putting less soda or juice in a 20 ounce cup:

"I think it could cost tens of thousands of dollars in replacing glassware for 10 restaurants. And we're not a chain we're a family run business. We're not a large corporation. So, it will take effect but we'll absorb the cost and try not to trickle it down to our customers."
